Question

What is the slope of a line perpendicular to the line whose equation is 2x+3y=21. Fully simplify your answer.

Answer 1

Answer:

3/2

Step-by-step explanation:

$2x+3y=21 \\ \\ 3y=-2x+21 \\ \\ y=-\frac{2}{3}x+7$

The slope of the given line is -2/3, and thus the slope of the perpendicular is 3/2.
